IT03570: ASSERT WARNING TRYING TO FREE EXTENT FOLLOWING FAIL-OVER AND FAIL-BACK OF HDR PAIR WITH INTERRUPTED DEFRAGMENT OPERATION

APAR status

• Closed as program error.

Error description

• An Assert Warning message of the following form may be seen in
  the online log during start up of the primary server in an HDR
  pair when a fail-over to the secondary has occurred followed by
  another fail-over back to the original primary:
  
  17:08:57  Assert Warning: Error trying to free extent.  Chunk 2,
  Page offset 29535, Number of pages 11984
  
  The accompanying AF file includes this stack for the thread
  "defragclean"
  
  afstack
  afhandler
  afwarn_interface
  chfree
  rs_defrag_dealloc_unused_pages
  ptalloc
  flalloc
  flalloc
  rspnopen
  defragmenter_clean_thread
  th_init_initgls
  startup
  
  This situation may arise when a table or partition defragment
  operation is interrupted by the shutdown of the server. The
  table or partition on the server where the AF arises becomes
  unusable and further partitions in the same dbspace may also be
  affected. The same partitions on the other server are unaffected
  by this problem.
